I loved this! Normally I don't read Mormor, but I've just written a crack one and it put me in the mood for some more, so I did some searching - this is my favourite characterisation of their relationship by far! I think you've got their characters down perfectly :D

This is amazing! Their relationship is so raw, and so believable. That last line is just heartbreaking.

poor Jim! and poor Seb, but he still loves him and cares for him!
I love this. Wonderful atmosphere, the night, the moonlight... and the ending broke my heart :'(
